c++ - how does readyRead() work in Qt? -

-

This is my first question on this website!

I have a problem reading a dump from a comm port, I send a complete message from another com port, and when I get it from Qt, it is always cut in many subpages . 

  Zero SerialPortReader :: init () {connect (m_serialPort, SIGNAL (readyRead ()), this, slot (readData ())); } Zero SerialPortReader :: readData () {// m_serialPort-> Waiter Reid (200); QByteArray Byte = m_serialPort-> ReadAll (); QDebug () & lt; & Lt; Bytearray; If (Baitarekstartsvith (Sof) and amp; Baitareyreds (Aofaiels) and Baitareaijh () & gt; = MIN_SIZE_DATA) {Dikoddeta (Baitare. Constdeta ()); } And {qDebug () & lt; & Lt; "LIB SWCom: Invalid Tram!"; }}

Sent messages are 25 or 27 bytes long, if I use a hybrid to read or read them, then I have no problem. If I use 2 emulated serial port to use COM, then I do not have this problem ... It only happens with the QT reading system and 2 physical COM portes ...

It seems that I'm not ready when the Reed Signals are extinguished ...

I am very confused, thanks in advance for your help!

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
